The Problem;
You have a problem opening a ACA/AMEP project or slow application start-up (I’m talking 10+ minute slow) on a given machine. This is specific to a user/machine and others using the same project are OK.
A possible cause;
The problem may be a bad personal Project Profile.aws file. By default Tool Palette Group information is written to the profile.aws files in the current user profile. This action only occurs when you open a project in the Project browser.
If the .aws is corrupted it can cause an error when the project is accessed by that user. If the project was active when ACA/AMEP is closed down the next startup will also be very slow or fail.
A Fix;
Deleting the users personal ProjectProfile .aws file for the problem project will restore access on that machine. With ACA/AMEP closed browse to this folder in explorer;
%userprofile%\Application Data\Autodesk\[ACA/ADT version]\enu\Support\Profiles\ProjectProfiles
You’ll see a non-project profile “ADTNonProjectProfile… .aws” and project specific profiles with names like “204DA426_95AA_49B6_A42E_4AB29C169962.aws”.
Make a copy, so you can restore if needed, & delete the .aws file. You can delete them all or open each.aws file with Notepad to see which project it relates to. The “Name=” value will match the project name. Then just delete the problem project’s .aws.
If I've had any problems with start-up on a given project & specific machine it's helped.
